Answer:
28cm
Step-by-step explanation:
Area of a parallelogram equals the base length, which is y cm, multiplied by the height, which is 18cm.
So
Area= 504cm
y cm (base) x 18 cm (height) = 504cm^2 (area)
y cm = 504cm^2 / 18cm
y cm = 28cm

The measures of the angles of the isosceles triangle are 55, 55 and 70.
Explanation:
An isosceles triangle has two congruent base angles and a vertex angle.
Let
b
=the measure of one of the base angles.
Let
v
=
the measure of the the vertex angle.
The vertex angle is 40 degrees less than the sum of the base angles.
